Solved 0 - Object of class std error after posting

thank you. I shall do that!
The big also exists when using the default cassiopeia template too

So the message after turning on debus is as follows:
Object of class stdClass could not be converted to string

So, My friend suggested to put this into chatgpt and see if it can work out whats going on.
I did just that and got this as a conclusion:
Conclusion
It seems that the error is related to how Kunena is interacting with the community plugin to post user activity after a reply. Most likely, the problem is caused by invalid user data or a misconfiguration in the integration. Check the user session, validate user data, and ensure the community plugin is correctly configured and compatible with your setup.


I disabled the plugin and the error went away. Is the plugin (Kunena - JomSocial Integration) out of date?

Hello,

I need to check, because i don't use Jomsocial and i have jomsocial 4.8.2, i will see if i'am able to reproduce the issue

I could perhaps ask if I can send you a copy of the latest version for testing purposes as its a paid-for extention

Thanks if you can ask it

I have just tried with the 4.8.2, it show plenty of deprecated messages but when i reply to a message i don't get this error
